Abstract
PURPOSE: To use a screen for several purposes by providing a scroll function to only the specific column or row region of the screen and by displaying variable data in the region with the scroll region and fixed data in other regions.
CONSTITUTION: The CRT display unit is equipped with selector (l) and scroll- address generating circuit (m) [shown by slanting lines]. Then, outputs of row- address counter (i) and scroll-address generating circuit (m) are alternated and used [the alternation output becomes the row address of refresh memory (c) through row-address selector (b)], thereby making partial scrolling on the screen possible. Next, when only the specific region is provided with the scroll function, state (a') before scolling changes into (a) and (b) after it. Figure (a) shows the scroll with 1st column to 32nd column taken as the scroll region, new data are displayed from the 1st column to 32nd on the 16th line, and the right half, namely, the 33rd column to 60th column are displayed on the same line without being shifted even after the scrolling. On the other hand, (b) shows the scroll with the 2nd column taken as the scrol region.
